I think some of the opencsw machines actually move or remove gcc, but maybe a bit of testing and autoconf-like probing and we can always find it.. or maybe it comes with static libgcc.a, and maybe therefore we can/should build static libgcc.a with cm3cg. Anyway, I'll be quite pleased if if I can get Darwin/Linux/*BSD working, Solaris can wait quite a while..<br><br> - Jay<br></div> </body>
